nnnn DESCRIPTION
The MB91401 is a network security LSI incorporating a Fujitsu’s 32-bit, FR-family RISC microcontroller with 10/
100Base-T MAC Controller, encryption function and authentication function. The LSI contains an encryption
authentication hardware accelerator that boosts the LSI’s performance for encryption and authentication commu-
nication (IKE/IPsec/SSL) to be demanded further.

MB91401 nnnn HANDLING DEVICES Preventing Latch-up When a voltage that is higher than VDDE and a voltage that is lower than VSS are impressed to the input terminal and the output terminal in CMOS IC or the voltage that exceeds ratings between VDDE to VSS is impressed, the latch-up phenomenon might be caused. If latch-up occurs, the supply current increases rapidly, sometimes resulting in thermal breakdown of the device. Use meticulous care not to let any voltage exceed the maximum rating during d
